MPL3115A2

I²C precision pressure sensor with altimetry

Rev. 8 — 12 April 2018

Data sheet: technical data

1 General description

The MPL3115A2 is a compact, piezoresistive, absolute pressure sensor with an I²C

digital interface. MPL3115A2 has a wide operating range of 20 kPa to 110 kPa, a range

that covers all surface elevations on earth. The MEMS is temperature compensated

utilizing an on-chip temperature sensor. The pressure and temperature data is fed into

a high resolution ADC to provide fully compensated and digitized outputs for pressure

in Pascals and temperature in °C. The compensated pressure output can then be

converted to altitude, utilizing the formula stated in Section 9.1.3 "Pressure/altitude"

provided in meters.The internal processing in MPL3115A2 removes compensation and

unit conversion load from the system MCU, simplifying system design.

MPL3115A2's advanced ASIC has multiple user programmable modes such as power

saving, interrupt and autonomous data acquisition modes, including programmed

acquisition cycle timing, and poll-only modes. Typical active supply current is 40 μA per

measurement-second for a stable 10 cm output resolution.
